Leakage Assistant - Dräger Zeus Infinity Empowered Instructions For Use Manual

Leakage assistant

The Leakage assistant facilitates leak detection in
the breathing system. Test pressure and leakage-
flow values are displayed continuously, so that a re-
duction in the leakage is immediately apparent by
manually checking the connections.
Test details
Starting the leakage assistant:
Touch the Leakage assistant button (A). The
Start button (B) turns dark green automatically.
The leakage assistant starts.
The test pressure is 25 to 30 mbar and indicated in
the form of broken lines on the pressure display.
If the patient subsystem is the cause of the leak, a
leak value above 100 mL/min is displayed in red.
For other causes, a leak value above 500 mL/min is
displayed in red.
A message indicates where the cause of the leak
can be found and provides information about how
to remedy the problem.
Leaving the leakage assistant:
Touch the Cancel button (C).

Leaks up to 100 mL/min are tolerated.
– The leak value is relevant to automatic ventila-
tion.
Leak test 2:
– Leak test in the system as a whole. Leaks up to
